Abstract
A three-piece solid golf ball having good shot feel and excellent rebound characteristics, while maintaining the characteristics inherent to the solid golf ball, i.e., excellent flight performance and good durability, wherein the gold ball has a core, an intermediate layer formed on the core, and a cover covering the intermediate layer. The core has a diameter of 30 to 36 mm and a specific gravity less than that of the intermediate layer; a ratio of the intermediate layer-covered core deformation amount/the core deformation amount within the range of 0.75 to 1, and a golf ball having a deformation amount of 2.3 to 3.5 mm, all deformations being measured when applying a load of 130 kgf.
